5 Key Takeaways

• 1

  AI-designed protein binders improved CAR T cell activity against tumors compared to antibody-derived binders in a mouse model of multiple myeloma.

• 2

  The study involved generating and screening 1,758 de novo binders targeting BCMA, CD19, and CD22 using various assays and mouse models.

• 3

  Three main issues were identified: tonic signaling, inaccessible binding sites, and off-target activity, which were addressed through computational and experimental methods.

• 4

  The optimized binder B5.I0 demonstrated superior tumor growth control in mice compared to existing BCMA-targeting CAR T therapies.

• 5

  The research highlighted the potential of evidence-based design over traditional methods in developing effective CAR T cell therapies.
